The VS-2.2 and VS-3.6 can also be deployed from helicopters. It was produced by Valsella Meccanotecnica and Singapore, but production has ceased. The VS-2.2 and VS-3.6 are essentially the same, the VS-3.6 being slightly larger, the SH-55 is larger still and has a more rounded appearance. A smaller mine, the VS-1.6 also uses the same fuze.
Logical layout. Each VPLEX engine in a cluster consists of two redundant IO directors and one IO annex, each being a single rack unit (1U) physical device. Each engine has 32 Fibre Channel ports (the VS1 model 16 front-end ports and 16 back-end ports) or 16 Fibre Channel ports (the VS2 model has 8 front-end ports and 8 back-end ports) and is protected by two redundant stand-by power supplies.
The VS-1.6 is an Italian circular plastic-cased scatterable anti-tank blast mine. It has very few metal components and is resistant to overpressure and shock. It has very few metal components and is resistant to overpressure and shock.
So OS/VS1 and SVS in principle had the same disadvantages as MFT and MVT, but the impacts are less severe because jobs and operators could request much larger partitions with a 2 KiB granularity (for OS/VS1) or regions with a 4 KiB granularity (for SVS), and the requests came out of a 16MiB address space even if physical storage was smaller.
There are several reasons that IBM provided a system generation process rather than simply providing a mechanism to restore the system from tape to disk. System/360 did not have self-identifying I/O devices, and the customer could request installation of I/O devices at arbitrary addresses.
Operating System/Virtual Storage 1, or OS/VS1, is a discontinued IBM mainframe computer operating system designed to be run on IBM System/370 hardware. It was the successor to the Multiprogramming with a Fixed number of Tasks (MFT) option of System/360 's operating system OS/360 .
In 1974 IBM announced release 2.0; that release and all subsequent releases became known as Multiple Virtual Storage . All releases of OS/VS2 were available to no charge because the software cost was bundled with the hardware cost. OS/VS2 Release 3.8 was the last free release of MVS. In the late seventies and early eighties IBM announced:
A soldier examines two inverted VS-1.6 blast-resistant anti-tank landmines. Cut-away view of a VS-MK2 blast-resistant anti-personnel mine. A blast resistant mine is a landmine (intended for anti-tank or anti-personnel purposes) with a fuze which is designed to be insensitive to the shock wave from a nearby explosion.
